We've successfully engineered giant robot arms for building cars on an assembly line. But smaller mass-produced items—like electronics—still mostly rely on the nimble hands and fingers of a human. Building and controlling robots on a very small scale is still very difficult, but a company called SRI International may…

It may not be a planet, but Pluto's got moons to burn. Astronomers using the Hubble Space Telescope have spied the icy orb's fifth satellite. Everybody, say hello to S/2012 (134340), or "P5" for short.

People's #1 fear when shaking the hand of a robot: having it mash their digits like Popsicle sticks. Two Stanford grad's solution: coat the robo-hand in the same material used in touch-screen phones to give it a precision grip.
